On 9.6 no.
She needs a CFW, and for that she needs a downgrade to 9.2 and at least an emuNAND.
Then, I'd recommend a9lh since it's just faster and safer (once installed) than menuhax, but your choice.

Also, I'd recommend you to switch to Luma instead of rxTools which is dead and not maintained anymore, which means that yeah, it works and "it ain't broke" but it won't necessarily always work as well.
